Application filed october 23, 1907. serial No. 398,853.

To all whom it may concern:

Be it known that I, SAMUEL G. GILLELAND, 1

a citizen of the United States, residing at Spring Garden, in the countyof Miller and State of Missouri, have invented certain new and usefulImprovements in Baling-Presses, of which the following is aspecification.

This invention relates to baling presses, and my obj ect is to roduce amachine of this character equippec with means for automatically forcingthe baling material from the hopper into the baling chamber and forfolding the loose ends of the material at the rear end of the bales.

A further object is to produce means for efficiently and reliablywithdrawing the baling plunger to its initial position in the event thatit should stick in the baling chamber.

With these general objects in view and others as hereinafter appear, theinvention consists in certain novel and peculiar features ofconstruction and organization as hereinafter described and claimed; andin order that it may be fully understood reference is to be had to theaccompanying drawings, in which- Figure 1, is a plan view of the balingcase of a baling press equipped with a self feed mechanism embodying myinvention. Fig. 2, is a side elevation of the same. Fig. 3,

is a vertical section on the line III-III of Fig. 1. Fig. 4, is avertical section taken on the line IV-IV of Fig. 2. Fig. 5, is a planview of thepower end of the press equi ped with means for effecting therecoil o the plunger and the return of the feeder operating mechanism toposition for again operating the feeder. Fig. 6, is a side view of theconstruction embodied in Fig. 5. Fig. 7, is a detail perspective view ofa part of the feederoperating plunger. 4 Fig. 8, is an enlarged verticalsection showing the crank arm of the feeder capable of swinging in onedirection independent of the feeder shaft to permit the feeder operatingplunger to return to its initial position.

In the said drawings, 1 indicates the baling case of a press providedwith afeed opening 2, in its upper side and with a hopper 3 havin itsrear wall vertically slotted for its ful height to provide the opening 4hereinafter referred to.

5 is the usual or any preferred type of plunger for operation in thebaling case and 6 the plunger bar terminating in a fork 7 at its frontend to receive the grooved wheel 8 mounted on a shaft 9 journaled instandards 10 at the front end of the baling case, the front end of thearms of the fork being pivotally connected by bolt 11, carried by lugs12 projecting from wheel 8.

13 is a grooved segment secured rigidly on shaft 9 and 14 is a cablesecured peripherally to said segment and engaging and underlying agrooved guide roller 15 carried by a bracket 16 projecting from thebaling case structure. From roller 15 the cable extends toward the powerend of the press and at such end terminates in branches 17 engaginganti-friction rollers 18, mounted in a bracket 19 secured on theframework 2O of the power end of the press.

21 is a horizontally arranged wheel adapted to turn with or upon shaft22. In the event that the machine is operated by an engine it will be inthe form of a gear wheel with its teeth 23 preferably disposed upwardand adapted for engagement by a' driving pinion 24. In the event thatthe operation is by horse power, said wheel will be provided with asweep, not shown, whereby it will be turned. The wheel or shaft willalso be equipped with any suitable means, not shown, for alternatelypulling forwardly on and releasing the cable 25, engaging wheel 8 andattached at its rear end to bolt 11, as

shown in Fig. 1, which means as it forms no part of the presentinvention has been omitted from this application, it being apparent thateach time said cable is drawn forwardly it rotates wheel 8 in thedirection indicated by the arrow and causes the plunger 5 to make thecompression stroke. The head of the arrow in Fig. 2 indicates thepreferred point which the front end of the bar or beam 6 attains at theend of such power stroke, and as it attains such point, the cable 25 isreleased to permit the plunger to be withdrawn as hereinafter explained,to its original position.

The framework 20, Figs. 5 and y6, is equipped with brackets 26 providedwith rollers 27 for engagement with a horizontal annular flange 28projecting from wheel 21, to prevent any tilting thereof.

29 indicates a pair of diametrically opposite teeth projecting upwardfrom flange 28 of wheel 21 for alternate engagement with a loop 30secured to the 'front end of the branches 17 of cable 14 at the frontside of bracket 19 so that said bracket shall limit the rearwardmovement of saidloop and in connection with said branched cables hold itin position for successive engagement b vsaid teeth. Just forwardfwithrespect to t ie direction of rotation of the wheel) of the abrupt faceof each tooth 29, the flange 28 is provided with a slot 31 occupied bythe horizontal arm 32 of an angle llever pivoted at 33 to said flange,the other arm 34 of the angle lever depending so as to strike the lug orpin 35 projecting upward from frame 20, said engagement operating theangle lever and causing its arm 32 to rise and force the loop 30 upwardand trip it from engagement with tooth 29. v

Referring now to the baling case end of the press, 36 indicates a pairof vertically slotted brackets securedto the side walls of the hopper atits rear lower cornersand 37 a pair of springs secured to said bracketsand holding downward therein a transverse shaft 38 journaled in thebrackets. To this shaft is rigidly secured in any suitable manner thefeeder, preferably consisting of a plate 39 having arms 40 andstrengthened or stiifened by a pair of bars 4l secured to said arms andplate in any suitable manner, the arrangement of the feeder being suchthat when it A'is swung downward to its horizontal position as shown inFig. 3, it depends through opening 2, to about the plane of the uppersurface of the plunger 5, and the customary apron 42 projectingforwardly therefrom. i To relevate the feeder it is connected by aretractile spring 43 to a bracket 44 secured to the baling case in anysuitable manner, though it is obvious that the relevating spring may beotherwise arranged to accomplish the same purpose. Secured to onenend ofthe feeder shaft 38 is a key 45, and j ournaled upon said vshaft is acrank arm 46 provided with a slot 47 to engage the key for a purposehereinafter explained, and the crank arm is provided at its rfree endwith a roller 48.

49 indicates a reciprocatory bar ,supported at the side of the balingcase occupied by crank arm 46 by and between anti-friction guide rollers50 and 5l, the former at least being of the grooved type to preventlateral movement of said bar, which by preference is of angle iron toinsure Ithe requisite rigidity without undue weight and said bar ispivotally connected by a link 52 to thel outer end A of a crank arm 53secured to shaft 9 outward by preference of segment 13, so that said barshall reciprocate in unison with the plunger. At its rear end the barhas a curved cam end 54, the same curving about concentrically of thefeeder shaft when the bar 49 is totally withdrawn. Said bar is alsoprovided at its inner edge with an upwardly projecting rib 55terminating at vthe rear end of the slot 56 in the inner edge -of thebar, as shown in Fig. 7.

In practice the parts initially occupy the position shown most' clearlyin Fig. 2,

. dentally start the reciprocatory bar 49 in the same direction, thecurved cam surface 54 of i said bar by pressure on roller 48 swingingthe feeder down so as to compress the baling material, not shown, in thehopper down into the baling chamber. In this operation the rollergradually rides upward on cam surface 54, and at the same time is pushedin the direction indicated by the contiguous arrow,

Fig. 2, the cam surface consequently insuring a longer movement of bar49 to effect the depression of the feeder than would be the case if therear end of said bar was abruptA instead of in the form of a cam. By thetime roller 48 attains a position upon rib 55 the feeder is de ressed tothe position shown in Fig. 3 and t e plunger has also attained theposition shown 1n Fig. 3 so as to prevent any possibility of the feedermoving down into the baling oase to a position where it would be struckby the plunger. The movement of the plunger continues after the feederhas forced the baling material into the case ahead of it and the feederis held depressed to prevent the baling material bulging up through thefeed opening under the pressure of the plunger, until the latter hasreached the rear end of the feed opening. As this position is attainedby the plunger rib 55 passes roller 48, and permits spring 43 toinstantly relevate `the feeder and permit the attendant to begindepositing a new charge of baling material into the hopper, the crankarm 46 soy swinging down through slot 56 in the inner ment the front endof rib 55 strikes roller 48,

and swings the same upward without affecting the position of the feeder,said. arm swinging upwardly sufficiently high to accommodate the forwardmovement of the rib because of the slot 47 receiving rib 45 (see Fig.8). As soon as bar 49 is withdrawn to its initial position the swing armdrops down to its original position so as to be ready for the neXt powermovement of the feeder and bar 49, it bein arm thus rops to its originalposition 'the lug 35 operates an le lever 34 and causes the same to tripthe oop 30 from engagement with the said tooth 29, the said cable beingdrawn back to its original position as shown in Figs. 5 and 6 under theensuing power stroke of the plunger and feeder operating bar 49. Allsubsequent operations are repetitions of Vthose described.

It will be noted that the shaft of the feeder understood that as suchcrank and the lower end of the latter always occupy a position below thetop of the baling case and because of this forms an abutment for theupper end of the bale in the event that it bulges backward upon thewithdrawal of the plunger and incidentally acts as a folder for thebaling material so that the upper ed We or corner of the bale shall becomparatively smooth and even. It will also be apparent by reference toFigs. 2 and 3 that the feeder is capable of yielding upwardly in theevent that it cannot make its full downward stroke because of theresistance of an overcharge of baling material, this yielding of thefeeder reducing chance of injuryfrom the cause named to the minimum.

From the above description it will be apparent that I have produced abaling press embodying the features of advantage enumerated and I wishit to be understood that I do not desire to be restricted to the eXactdetails of construction shown and described as obvious modificationswill suggest themselves to one skilled in the art.

Having thus described the invention what I claim as new and desire tosecure by Letters-Patent, is
